To all whom it may concern:

Be it known that 1, MICHAEL J. MILMIOE, a citizen of the United States, residing Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cartoning Machines, of which the following is a specification.

This invention relates to machines for opening collapsed cartons, filling, closing and sealing the cartons, and for detecting any cartons not properly filled, and has for its objecmthe provision of mechanism of the class named which shall be of improved construction and operation.

bination and he invention is exemplified in the comarrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims. Y

In the embodiment of the in vention shown in the drawings, the mechanism is adapted the closing mechato open a carton from its flat folded position, insert a number of articles in the carton, ascertain if there is any shorta e of the articles supplied to the carton," c ose an sealthe carton, and collect the cartons-in a receiver where they are held until they can be conveniently removed. It will be readily understood, however, that the invention is applicable to various forms of machines other than that illustrated by way of eit-v ample.

form of carton for which the illustrative embodiment of the machine is adapted is shown at 1 in Figs. 41 and 43 and com-' prises a rectangular tubular body portion aving closing flaps extendm from the four walls of the carton at eac end thereof. The cartons are supplied -to the machine I from a magazine2 in which they are stacked the one upon the other in collapsed form, as illustrated in Fig. 20. The lower end of the magazine 2 is closed by spaced strips 3 on which opposite ends of the lowermost carton rest. A carrier in Fig. 1, is secured tothe end of a shaft 5 in a position to locate the periphery thereof directl between the supporting strips 3 beneath the lower end of the magazine 2. A pluralit of carrier blocks 6 are inserted in circum erentially spaced notches in the periphery of the wheel 4, and each block 6 is provided with transversely spaced teeth 7 and 8. The blocks 6 are held in place in the periphery of the wheel 4 by screws 9. The shaft 5 is journaled in a suitable frame member 10 and carries a worm wheel 11 at the. end thereof opposite the carrier wheel 4, as shown in Fig. 2. The worm wheel 11 meshes with a worm 12 on a shaft 13 journaled at 14 and 15 on the frame 10. A spur gear 16 is loosely mounted on the end of the shaft 13 and is driven by a mot0r17. clutch 18 operated by a lever 19 is provided for securing the spur gear 16 to the shaft 13 for. driving the shaft. A hand wheel 20 is also secured ,to the shaft 13 so that the shaft may be turned by hand for shifting parts of the machine when desired.

As shown in Fig. 17, the front wall 21 of the magazine 2 terminates slightly above the upper face of the supporting strips 3 leaving a slot of sufficient thickness to permit of the disclfarge of a single carton from the magazine. The" teeth 7 and 8 on the blocks 6 areof sufficient length to project slightly above the upper face of the strips '3 as they are moved between the strips by the rotation of the wheel 4. As the front face of the teeth 7 and 8 approach the rear face of the magazine the upper "portions of the teeth will engage the rear edge of the lowermost carton, as shown in Fig. 18, and

1 further rotation of the wheel will cause the wheel 4 and thus move the carton forwardly with the teeth to carry the carton from the d are beveled and the teeth tinues to rest upon disc or wheel 4, as shown A that upward positively force it magazine throu h the slot beneath the lower edge of the wa 21. As shown in Figs. 18 and 19, the rear portions of the teeth 7 and 8 are sufficiently close together to permit the forward edge of a carton to rest upon the beveled upper face of one set of teeth whileit is being moved forwardly by the next succeeding teeth. The position of the carton as it moves away from the magazine is illustrated in Fig. 20 and. as soon-as the rear edge of the carton moves off of the supporting strips 3 that edge will tend to drop into the notch between the teeth, while the front edge conthe beveled upper face of the preceding pair of teeth. This posi tion of the carton is illustrated in Fig. 21. To insure movement of the rear edge of the carton into the notch between ,the teeth an arm 22, Fig. 45, is provided having a plate secured to the end thereof. The plate 23 is. cent-rally positioned relative'to the front of the magazine 2 and lies adjacent the outer edge of the front wall 21 which wall extends approximately only half-way across the front of-the magazine. The arm 22 is secured to a sleeve 24 on a stud. shaft 25-carried by theframe 10, as shown in Fig. 45. A second arm 26 is secured to the sleeve 24 and is connected by a link 27 to an arm 28 pivotally mounted at 29 on the frame 10, as shown inFig. 7. The arm 28 is connected by a link 30 to an arm 31 secured to a shaft 32 'ournaled for oscillation on the frame 10. T e shaft 32 carries at its opposite end an arm 33, as shown in end of the arm 33 being pivotally connected at 34 toan upright rod 35(\ The upright rod 35 asses loosely through a sleeve 36 on the en of an arm 37 and is provided with an adjustable collar 38 and a spring 39 so movement of the collar 36 produces a positive oscillation of the shaft 32 in one direction, while downward movement of the sleeve 36 produces a yielding movement of the direction. The end of the arm 37 opposite the sleeve 36 is provided with a bearing 40 'pivotall mounted on a shaft 41 suppog'ted cam 44 periodically imparts a resilient downward movement to the late 23 through the chain of mechanism escribed,

so that the plate 23 is brought into the position shown in Fig. 21, causing the curved face 45 thereof to engage the carton 1 and into the notch between the teeth 7 and 8. As the plate 23 is moved into the position shown in Fig. 21 its rear edge will engage the frontedges of the c'ar-.

thus readjusting the cartons in the magazine previous to the loo 1 Fig. 6, the a shaft 32 in the opposite edge of secured to th 1. The plate 47 the opening operation by the pin 1 I movement of the next carton by the succeedin%pair of teeth.

uring the movement of the carton into the notch between the teeth 7 and 8 by means of the plate 23, the opening of the carton is one end thereof through the action of a pin 46 carried on the end of a plate 47 e outer side of the magazine-2 end thereof, as shown in Fig. is removed in Figs. 17 to 23 to permit better view of the other parts. shown in Fig. 45,-the inner end of the pin 46 is sharpened and projects below the the outer end flaps of the cartons 1 as the cartons are being moved into, the notches between the teeth 7 and 8.

As shown in broken lines in Fig. 45, the lowermost end flap of the carton 1 is provided with a cut-away portion or notch 48 at the lower so that as the carton moves downwardly the pressed downwardly at its central to open the flap at one end, while the opposite end remains closed. The beginning of 46 is shown in Fig. 2

To continue the opening process a pair of fingers 49 and 50 are provided which are supported 'by'a bar 52.

in Fig. 45, which shaft is provided at its opposite end with an arm 54, shown in Fig. 2. A rod extends loosely through a sleeve 56 on the end of the arm 54and is provided with a spring 57 for imparting resilient upward movement The lower end of the rod Fig. 10, passes through a arm 59. he opposite end provided with a bearin the shaft 41. A cam rol the arm 59 and face of the cam 55, as shown in sleeve 58 in an of the arm 59 is 60 journaled on er 61 is carried by -engages a groove 62 in the wheel 44.0pposite the groove A spring 63 is interposed between the sleeve 58 and a collar 64 adjustably mounted on the rod 55. otat-ion of the cam 44 imparts resilient movement to the fingers 49 and 50 to the leftin Fig. 20, and positive return movement in the opposite direction. The fingers 49 and 50 are shown in their extended position to the left in Fig. 21 in position they come into engagement with the front edge of the carton just as its in the notch between the teeth 7 and 8. It will be seen fromFig. 45 that the finger/59m slightly so that the conedge of the carton slightly in advance of the engagement with the corresponding shoulder'66 on the finger 50.

h his compression of the carton will continue the opening operation, which opening will progress from one end of the carton to the as shown in Fig. 22, for the reason that the greater length of the finger 49 will compress theou'ter end of the carton in advance of the inner end thereof.- This 'method of operation greatly facilitatesthe It is not only easier opening of the carton. to start the openlng at one end and continue the movement lengthwise to the otherend of the carton, but this method of operation prevents buckling of both sides of the carton in the same, direction, and also permits the curve in the carton Wall formed by the opening pressure, to travel continuously from one end of the wall to the other. 'If opening were started simultaneously at both ends of the cartonntwould frequently happen that when both endsof the upper wall started to bend in an upwarddirectwn central portion of t e upper wall will bend downwardly so that when the two opening movements meet one another at the center of the carton there is a transverse bueklin in the upper wall of the carton, tendin be opening proprogressive way which runs smoothly from one end to the other until the carton is brought into its correct rectangular formation. the carton has been. substantially opened by compression between the fingers 49 and 50 and the teeth 7 and 8 the forward edge of the carton is brought into engagement with the curved front face 67 of a guide rib 68 which extends around a portion of the periphery of the wheel 4 concentric therewith. The curved face 67 of the rib 68 completes the seating of the open carton in the space between the teeth on the periphery of the cartons fit sufficiently closely between the.

i the runways 72. The blade teeth in the periphery of the Wheel to be frictionally held, but they are positively retained in place by the concentric retaining rib 68 which is supported on the frame by screws 69, as shown in Figs. 1 and 31 The filling operation occurs while the cartons are passing a position substantially on a level with the axis of the wheel 4.- hile the cartons are passing the filling position they are held against endwisemovement by a flange 70 carried by a block 71 which is secured to the retaining rib 68, as shown in This flange extends between the side flaps of the cartons and engages the edge flaps andbends them over, as shown best in Fig. 43, so that the lowermost flap of each carton forms a stop for limiting the movement of material fed into the carton.

The material with which the cartons are filledis supplied from a series of runways or chutes'72 secured to the frame 10 and extending vertically, as shown in Figs. 1 and 3.

The upper ends of the run-ways 72 may be connected with a supply hopper from which the material is supplied to -the runways. The mechanism in the embodiment illustrated is arranged for handling confections in the form of lozenges or briquets. but it will be apparent to those skilled in the art that the mechanism may be adapted to a large variety of materials. The briquets are designated in the drawings by the numeral 73 and are held in place in the runways '72 by thin sheets or strips 74 secured to partitions 75 which separate the runways. For supporting the briquets in the runways 72 a blade or plate 76 is carried by an arm 77 which is secured to a stud 78 pivotally mounted on the frame 10, as shown in Fig. 7. A, spring 79 presses the blade 7 6 into position beneath the columns of briquets in 77 is periodically swung rearwardly against the tension of the spring 79, by mechanism to be described, a sufficient amount to permit one briquet to drop from each of the slideways 72 onto a ledge 80, Figs. 13 and 43, formed on the front face of a filler head 81. The briquets thus deposited on the ledge 80 are held in place by a door 82 hinged at 83 to a bracket 84 secured to the lower face of the head 81. A'latch 85 is provided for normally retaining the door 82 in closed position, the purpose of the door being to permit access to the ledge 80 when occasion requires.

The tiller head 81 is carried on an arm 86 pivotally mounted on the shaft 5, as shown in Fig. 8, between the frame 10 and the wheel 4. A web 87 extends from the edge'of the arm 86 through an opening in the frame 10 and supports a guide track 88 in rigid relation with the filler head 81. A slide block 89 is mounted to travel in the guide track 88 and is connected by a bar 90 with a head 91, as shown in Figs. 6 and 8. The slide block 89 carries a stud shaft 92 on which a cam roller 93 is journalled to travel in a cam groove 94 formed in a block 95 secured o the frame 10. A red 96 is connected with the head 91 and has its opposite end extending through a sleeve 97 carried by an upright 98, as shown in Figs. 2 and 9. The upright 98 is provided with a sleeve 99 at its lower nd pivotally mounted on the shaft. 41 and carries a cam roller 100 which operates in a groove 101 formed in the face of a cam wheel102secureclto the shaft 13. The position of the rod 9601 the sleeve 97 is controlled by an adjustable collar 103 and a spring 104. The bar 90 extends through a slot 105 in the guideway 88 and a plunger 106 is secured thereto in position to slide along the ledge 80 when the head 91 is reciprocated' by the rotation of the cam 102. The cam groove 94 is so shaped that when the rod 96 is moved to the left, as viewed in Fi g. 9, the roller 93 will move downwardly carrying with it the guide track 88 and the filler head 81 which is rigidly connected therewith by=the web 87. At the same time that the filler head 81 is moved downwai'dly it will, of course, be constrained to rotate about the shaft 5 which is the axis of the carrier wheel 4, and the parts are so timed that the downward movement of the filler head will'impart the same velocity thereto as that of the wheel 4. The filler head begins its downward movement each timethat a carton 1s brought into position with the inner face of its front wall'in alinement with the ledge 80, as shown in Fig. 43, and the parts will remain in this relation during the forward movement of the rod 96 and plunger 106. During the time that the tiller head rotates in unison with the carrier wheel 4 and the cartons thereon, will be moi/ed by the cam. 102 and the rod 96 to carry the briquets 7 3 which have been deposited upon the ledge 80 into the open end of the carton. The position" of the plunger 106 at the beginning of its filling movement is shown in Fig. 43, and its position at the close of the filling movement is shown in Fig. 44., As the plunger 106 is retracted the filler head will be again moved upwardly into position to receive the next set of briquets deposited on the ledge 80 from the slideways 72. The gate 76 forgontrolling the deposit of the briquets upon the a cam 107 formed ledge 80 is operated by on the extended portion ofthe bar 90. The cam 107 engages a roller 108 carried by the end of a lever 109 pivoted at 110 on a block 111 carried by the frame 10. The end of the lever 109 opposite the cam roller 108 lies against the upwardly bent portion of the blade or gate 76 so that at the time that the rod 96 reaches its rearmost position the cam 107 will move the lever 109 to withdraw the plunger 106 the gate 76 and provided with a spring 123 'ingit away from the aaae eee briquets to be deposited upon the ledge 80.

operates against the tension of the spring 79' which normally holds the gate 76 closed with the arm 109 against a stop 113 which limits the movement of the gate 7 6"under the influence of the spring 79. At the time that the gate 76 is opened by the cam 107 the filler head with the ledge thereon will be in its uppermost position.

It may sometimes happen that the supply of briquets in one or more of the shdeways 72 has become exhausted, or the slidewa may be obstructed, or for some other reason a complete set of briquets may not be deposited upon the ledge 80. When this occurs the particular carton will, of course, be only partially filled and in order to prevent partially filled cartons from being sent to the trade it is desirable to provide a means for detecting the shortage. For this purpose a finger 114 is slidably supported in a block 115 and resiliently pressed outwardly by a spring 116 in the rear of the finger and a stop 117 is provided for limiting the outward movement of the finger-114. The block 115, as shown in Figs. 1 and 8, is pivotally mounted on a bolt 118 carried by spaced flanges on the upper end of an arm 119. A spring 120 resiliently presses the block 115 toward the supporting frame 10. A downwardly extending bracket 121 is secured to the block 115 and a plunger rod 122 Fig. 7. The plunger rod 22 is connected to the upright 98 and is normally pressbracket 121. When the upright 98 is moved to operate the plunger 106 it will simultaneously move the rod 122 to engage the bracket 121 and shift the finger om the position shown in Fig. 8 to the position shown in Fig. 42. Prior to the en gagement of the rod 122 with the bracket 121 the arm 119 will be rotated in a counterclockwise direction, as viewed in Fig. 1, to bring the end of the finger 114 into contact with the end fiap of the carton which is being filled, as shown in Fig. 41. tact occurs at the time 73 is entering the carton,

the requisite for filling the carton finger 114 W11 reach lies in the path of H ton, as sl carries the carton into contact with the inner 12 with the end. flap under these conditions there will be 'no briquet in place to back up the end flap and instead of compressin the spring 116 the movement of the bloc 115 will force the end flap into closed posi- 70 tion, as shown in Fig. 42. t the same time the rod 122 will engage the bracket 121 and swing the end of the finger 114 to the left,

as viewed in Fig. 42, so that the end flap will be tucked into the carton. If there are It no briquets at'all present on the led e '80 the end flap will remain thus close one or more briquets present it will and wi carry with time so as to hold the other end flaps.

During the filling operation the cartons are held against end t e cartons are free. Secured to'the guide rib 68 by screws 125 in position to engage we the ends of the cartons after ave passed beyond the block ere b it forwardly against iown in F eccentric relative v the projection 141 the lower ment with the guide 126. The shaft 32 is is rovided with a bearingsleeve 135 jour na ed on the shaft 41 and a cam roller 136 is'connected to the arm 134 in position to engage a cam groove 137 in a'lateral face of to the shaft 13. The

an adjustable collar 138' and a spring 139.

Rotation of the cam 102 will rock the shaft 128 through themechanism described for operating the arm 119 and the test finger 114 in themanner previously described.

The guide 126 is provided with a groove 140, which, as shown in Flg. .1, 1s shghtly to the wheel 4. When the carton first engages the guide 126 the upper side flap will pass within the groove 140, as'

shown in Fig. 27, and the lower side flap will extend below the rear of the plate 127, the gulde 126 --1s providedwith a downwardly extending pro- ,jection 141 which has the forward edge 142 thereof beveled inwardly toward the wheel 4, as shown in Fig. 28, so that when the lowermost side flap' engages the edge 142 it will be bent downwardly into the position shown in Fig; 29. At the same time the eccentric position of the groove 140 will cause the edge of the groove to engage the upper side flap and gradually turn it over until the flaps are brought into the position shown in Fig. 30. After the carton passes side flap engages a plate 143 having its forward edge 144 beveled so that the lower flap is bent backwardly against the outer face of the side wall of the carton, as shown in Fig. 32. At this position the curvature of the groove 140 has brought the outer edge of the groove with adhesive material. engages a plate 146 the into alinement with the outer face of the guide 126 so that the groove has its outer side open, except for the portion closed by the plate 144. As the lower side flap passes out of contact with the plate 143 it is brought into engagement with a glue roll 145, as shown in Fig. 33. where it is coated The glued flap next front edge of which is beveled and engages the flap on the side toward the guide rib 68, as shown in Fig. 34, and swings the flap outwardly into the position shown in Fig. 35','so that the flap is again in position to enter the groove 140 in the manner illustrated in Fig. 36. The guide 126 is provided with a second projection 147 which forms the lower edge of the groove 140 beyond the plate 146. The concarton will remain: open at the plate 127. Adjacent cartons with since the inner face of the lower sideflap is now covered with adhesive 'material the lower flap is sealed in place and holds the two edge, flaps and the upper side flap in closed position, thus completing the closing ofthe carton. The 'flaps at both ends of the carton are closed in the same way and since it is the lower. flap of the inner end of the carton which is tucked into the carton in case of shortage it will be apparent that in such case the lower flap wlll-not be in position to receive the adhesive material when it passes the glue roll and consequently there will be nothing to hdld the other flaps of the inner end of the carton closed and the one end so that the attendant may readily detect and remove any carton which is not properly filled.

the wheel 4 and the e'c- After the end flaps have been closed the the wheel 4. The guide rib 68 terradial direction away from the carrier wheel 4. The cartons are removed from between the teeth of the wheel by a pair of discharge arms 148, as shown in Figs. 1, 4, 39 and 46.

The discharge arms 148 arecarried bya sleeve 149 on the shaft 29 which is the same sleeve, that carries the arm 28 andthe discharge arms'are actuated by the oscillation of the shaft 29, previously described.

The cartonsare received from the carrier wheel 4 by a collector chain 150 having a series of pockets 152 formed of sheet metal channels secured to the links of the chain 150. The walls of the pockets 152 are so spaced that they bear against the ends of the cartons frictionally in the pockets, and the pockets are sufiiciently deep to permit the cartons to move in unison with the carrier wheel during discharge of the cartons from the wheel to the pockets. Lhe receiving pockets are successively brought into alinement with the discharge position of the wheel 4 and remain stationary in this position a sufficient lengthof time to receive the number of cartons that a particular pocket will hold. When one pocket has been filled the chain is moved \to bring the next sue-- ceeding pocket into receiving position. The cartons are fed .to the pockets while they are situated on the lower run of the receiving chain and remain in the pockets until they are carried to the u per run of the chain. This permits of s clent time for the adsufiicient pressure to hold the rescpoa 7 J K I I k 1 I hesive material to set before it becomes necare so timed that the movement of the chain essary to remove the cartons and 1t also 150 will take place after a sufficient numallows a very considerable capacity in the r .of cartons have been inserted in a rereceiving mechanism so that 1t is unnecesceiving channel 152 to substantially fill the sary for the attendant to remove the carchannel.
